ECZ 2018 · GCE Paper 1 — Circle Theorems
In the diagram, RWS is a tangent to the circle at W. The points V, W, X and Y are on the circle such that XŶW = 44°, VŴY = 54° and SŴV = 39°. Calculate RŴX.
- A. 39°
- B. 54°
- C. 43°
- D. 44°
Verified working — step 1
The angle between a tangent and a chord equals the angle in the alternate segment. Chord WX makes angle RŴX with the tangent, and the angle subtended by WX in the alternate segment is XŶW = 44°. So RŴX = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
